Using motion detectors and an Arduino you can trigger lights, ... A simple way to think of the sensor is a switch; the diagram below explains the difference between the two approaches.

It is likely that many of us will at some time have experimented with motion detectors. Our Arduinos, Raspberry Pis, Beaglebones or whatever will have been hooked up to ultrasonic or PIR boards whi… ...

It’s really hard to overstate how awesome ESP8266 development boards like the Wemos D1 Mini really are. For literally a couple of dollars you can get a decently powerful Wi-Fi enabled microco… ...

This is a firmware application written in C++ using Arduino and Adafruit libraries. It sleeps in low power mode until, activated by the motion sensor, it takes a picture. Images are posted to io ...

When everything’s plugged in, this is how your Arduino, motion sensor, and power relay should look. Jeremy S. Cook. Plug the male-to-female jumper wires into the motion sensor pins.

However, the microwave motion sensor module -HB100- introduced here makes the task sweet and simple. HB100 miniature microwave motion sensor is an X-band, Bi-static doppler transceiver module. This ...

You'll definitely need some gear for it—the Arduino for one, but also a PIR motion sensor, not to mention the (cleaned and rinsed!) Raid Power Sprayer motorized spray bottle.
